Fath al-Rabbani

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that Sayyiduna Umar (may Allah be pleased with him) acquired a piece of land called Thamgh from the Jews of Banu Harithah. Regarding this, he submitted to the Messenger of Allah (peace and blessings be upon him): O Messenger of Allah! I have obtained a valuable and excellent property, and I wish to give it in charity. Then, according to the command of the Prophet (peace and blessings be upon him), he gave it in charity in such a way that it would neither be sold, nor gifted, nor inherited. The wise people from the family of Sayyiduna Umar (may Allah be pleased with him) would supervise it, and whatever wealth remained after its expenses would be spent in the way of Allah, on travelers, for freeing slaves, on the poor, relatives, and guests. Its supervisor may eat from it in a good manner and also feed guests, but should not seek to amass wealth from it. Hammad says that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) used to send gifts from this land to Sayyiduna Abdullah bin Safwan (may Allah be pleased with him). Sayyidah Hafsah bint Umar (may Allah be pleased with them both) and Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) also gave their respective lands in charity just as their father, Sayyiduna Umar (may Allah be pleased with him), had done. The supervisor of the land of Ibn Umar (may Allah be pleased with them both) was Sayyidah Hafsah (may Allah be pleased with her) herself.
